I have done some work in the past transferring a printed survey to vector 
drawing file using Xara. This was bought by Corel at one point (it was far 
superior to Corel Draw at the time and did much the same thing) but I 
think they went independent again. It does excellent curve drawing and 
handles a vast range of scales so you can add detail down to mm on 
drawings which cover km.
I started with an A1 bitmap which was scanned in 2bit colour (true black 
and white) so whist the pixel count was very high the memory footprint was 
small. As a GIF file it fitted on a floppy disk. You can also import 
postscript files if you generate one from survex for the centre line. Then 
you can do all the passage detail drawing directly in Xara.

You can find Xara on Amazon. I think they call the current version Xara X.
